Does Change on the MOLEST and RAPE Scales Predict Sexual Recidivism?

The purpose of the current study was to examine whether the MOLEST and RAPE scales and change on these measures predicted sexual recidivism in a sample of 146 adult male sexual offenders who participated in a high-intensity treatment program while incarcerated. The majority of subjects had functional scores on the MOLEST and RAPE scales prior to treatment. Of those who had dysfunctional pre-treatment scores, the majority made significant gains. However, the MOLEST and RAPE scales did not significantly predict sexual recidivism. This was the case for pre-treatment scores, post-treatment scores, and change scores. Our findings are generally not consistent with the view that these measures assess dynamic risk factors for sexual recidivism. However, this is the first published study to examine the predictive validity of these scales and more rigorous research is needed before firm conclusions can be drawn.

Does change in hostility predict sexual recidivism?

The purpose of the study was to examine whether scores on a widely used measure of hostility--the Buss-Durkee Hostility Inventory (BDHI)--and change on this measure predicted sexual recidivism in a sample of 120 adult male incarcerated sexual offenders. Pre- and posttreatment scores, simple difference scores, and clinically significant change were examined. The majority of participants had functional scores on the BDHI prior to treatment. Of those who had dysfunctional pretreatment scores, the majority remained unchanged. Higher posttreatment scores on the Assault and Verbal Hostility subscales significantly predicted sexual recidivism. The remaining pre- and posttreatment scores as well as change scores and classifications did not significantly predict sexual recidivism. Our findings suggest that the Assault and Verbal Hostility subscales may be useful for predicting sexual recidivism but were not clearly consistent with the notion that the BDHI assesses a dynamic risk factor(s) for sexual recidivism. Due to a number of limitations of the current study, however, more rigorous research is needed before firm conclusions can be drawn.

Gender-specific genital and subjective sexual arousal to prepotent sexual features in heterosexual women and men.

Heterosexual women respond genitally to stimuli featuring both their preferred and nonpreferred genders, whereas men's genital responses are gender-specific, suggesting that gender cues are less relevant to women's sexual response. Instead, prepotent sexual features (exposed and sexually aroused genitals), ubiquitous in audiovisual sexual stimuli, may elicit automatic genital responses, thereby leading to a nonspecific sexual arousal pattern in women. To examine the role of stimulus potency in women's sexual response, we assessed heterosexual women's and men's genital and subjective sexual arousal to slideshows of prepotent stimuli (erect penises and aroused vulvas), non-prepotent stimuli (flaccid penises and female pubic triangles), and sexually neutral stimuli. Contrary to our hypotheses, both women and men demonstrated gender-specific genital and subjective sexual arousal, such that sexual arousal was greatest to prepotent male and female stimuli, respectively. This is the first study to demonstrate gender-specific genital responding in heterosexual women.

Observational stance as a predictor of subjective and genital sexual arousal in men and women.

Observational stance refers to the perspective a person takes while viewing a sexual stimulus, either as a passive observer (observer stance) or an active participant (participant stance). The objective of the current study was to examine the relationship between observational stance and sexual arousal (subjective and genital) across a range of sexual stimuli that do or do not correspond with a participant's sexual attraction (preferred or nonpreferred stimuli, respectively). Regression analyses revealed that, for men (n = 44), participant stance significantly predicted subjective and genital arousal. Women's (n = 47) observer and participant stance predicted subjective arousal but not genital arousal. Analysis of variance showed that participant stance was greatest under preferred sexual stimuli conditions for all groups of participants, while observer stance scores revealed a less consistent pattern of response. This was particularly true for opposite-sex-attracted women, whose ratings of observer stance were lowest for preferred stimuli. Observational stance does not appear to account for gender differences in specificity of sexual arousal; for men, however, participant stance uniquely predicted genital response after controlling for sexual attractions. Similarities in the relationships between men's and women's observational stance and sexual responses challenge previous claims of gender differences in how men and women view erotica.
